https://issues.dlang.org/show_bug.cgi?id=20700 Issue ID: 20700 Summary: Forward references leads to `extern(C++, class|struct)` being ignored Product: D Version: D2 Hardware: x86_64 OS: Windows Status: NEW Keywords: C++, industry Severity: major Priority: P1 Component: dmd Assignee: nobody@puremagic.com Reporter: pro.mathias.lang@gmail.com Consider the following code, compiled with DMD 2.091.0 on Windows x64: ``` extern(C++): version(Bad) void before(const ref Foo); extern(C++, class) struct Foo {} void after(const ref Foo); version(Bad) pragma(msg, "Before: ", before.mangleof); pragma(msg, "After: ", after.mangleof); ``` With no version, it outputs: ?after@@YAXABVFoo@@@Z Which is the correct mangling. However with `-version=Bad`: ``` Before: ?before@@YAXABUFoo@@@Z After: ?after@@YAXABUFoo@@@Z ``` -- |
